ReefAngel Dimmable Moonlight

I know this has to be here somewhere but I couldn't find it by topic in this forum. How many of these units would I need for a 6 foot tank.

You can only connect 2 of the dimmable moonlights on the standard RA as they use one PWM port each.
If you want to connect more of them, you will need the PWM expansion module.
For a 6 foot tank, I would suggest at least 4.
